I believe the answer would be C; but I'm not sure if this is the right category for this question?
I think that this an example of a paired t test. Since each student (subject) is given 2 treatments of the same material.
It would be: 178.90 * 3.75%
= 178.90 * 0.0375
= 6.71
In short, Sales tax would be $6.71
Hope this helps!
